“Breakaway” by Avril Lavigne (better known from Kelly Clarkson’s 2004 album of the same name)
Avril wrote the tune for herself way back in 2002 for inclusion on her album Let Go, but was determined to be “unsuitable.” But it was certainly good enough for freshly minted American Idol star Kelly, who turned it into a massive hit!
“Loved Me Back To Life” by Sia (better known from Celine Dion’s 2013 album of the same name)
Here’s a collabo we never expected! Sia’s tone steers the tune away from Celine’s adult contemporary country, and back into the pop world (where it belongs). The Australian singer also penned “Pretty Hurts” from Beyonce’s latest, as well as Rihanna’s “Diamonds.”
“Telephone” by Britney Spears (better known from Lady Gaga’s 2009 album The Fame Monster)
REMIX! Now for a little variation on the theme: Lady Gaga indeed wrote her duet with Beyonce, but not before offering it to Britney Spears years earlier for year Circus album. Brit apparently passed after cutting a rough vocal demo, but it all worked out fine for Mother Monster in the end. ”It’s fine because I love the song and I get to perform it now,” she said later.
